ANSWER:

You don’t need to allow such overthinking ruin your belief!

There can be tens of explanations for that. Insisting to be a detective and having the ability to doubt the hadeeth with your own logic is a dangerous thing that indicates the inability to submit your will and believe and rather liking to rebel and reject more than to believe. 

QUESTION: Are the hadiths in Muslim and Bukhari about the Last Hour coming on Friday and after the sunset are valid? While it is evening in one part of the world, it is daytime in another part of the world, and it may even be Friday evening in one part and Saturday morning in another part of the world. Aren’t these hadiths valid for Muslims living in those regions ?
